Application and october is, isos. sei-ai No. 523,452.

improvements in mininf* naehines and more particularly to that class ada ted to be used `or placer mining and our o ject is to provide a suitable separating wheel tor separating the larger.` from the smaller particles.

A further object is to provide means for digging the soil and conveying the same into the se Jarating wheel.

A Iurtlier object is 4to provide means for raising and lowering said digging device.

A further object is to provideniieans or conveying the smaller' particles of the soil through a chute' and onto a wheel comprised of eccentrically arrang 'd troughs. said chute and 'troughs having riilies therein.

A, further object is to direct the product, after leaving the rilie wheel, over :in amalgam plate and onto a revolving disk.

rovide means for conveying the larger foreign particles of the soil to a suitable discharging point.

A further object is to provide means for conveying the. smaller foreign particles from the disk to a suitable discharging point.

inrlhcr ohjectis to provide means for removing the smaller foreign particles from thr disk.

A still further object is to provide suitable .snppm'ting trucks for tle machine and a still farther object is to provide a driving mechanism for said trucks, wher-eh)Y the ma;

chine' may he mori-l back and forth when desired.

In the accompanying drawings forming part of this application. Figure l is a longiiudmal central sectional view through the. machine. Fig. 2 is a detail elevation of the separating wheel. showing parts t-lorcof broken away. lfilf Il is :i top plan View of thc ritllo wheel .sho '.:g the disk in position below the same. l"'.g. l is a detail sectional View of the combined digger and elevator as sten on line 4 4 Fig. 5, Fig. 5 is a top plan view of the end of the digger, Fig. G is a front elevation of the machine, and, Fig. 7 is a perspective View partly in section of the sepa ating wheel. Fig. S is a reduced top plan view of the rotatable disk with the spiral scraper as applied.

Referring to the drawings in which similar reference numerals designate corresponding parts throufrhoutthe several views, l indicates a tana, to the lower surface of which is secured a frame 2, to which vare rotatably secured a plurality of rollers 3, said rollers in turn hearing on a track 4. carried y a platform 5.

Positioned bel-ow the platform 5 are trucks G which are preferably arranged in pairs at each end of the platform and swish elly mounted thereon, the Wheels 7 being driven through the medium of a worm 8, which meshes with a gear 9 'xed to one of the axles l0, the worin 8 being attached to the lower end of a shaft l1, the upper end of which shaft, forms a pivotfor the truck and to said upper end is attached a sprocket- 12.

Power is applied to the gears connected with the axles l0 in any preferred manner as by means of a driving shaft 13, which extends upwardly through a beam 14, the upper end of the driving shaft having a. sprocket thereon, through the medium of which power may be applied to the driving shaft, while to thellower end of said driving shaft is attached a gear 16, which meshes with gears 1T on `auxiliary shafts 1S, the upper ends of said auxiliary shafts i having sprockets 1S) thereon which engage a sf Jcket chain 20, said chain heilig in turn extended the full length of the platftlrm 5 and around the sprockets 32 on the shafts 1l, hy which vmeans the wheels of both trucks will be driven in unison. Il. will likewise be seen that should the chain Q0 or other parts of the driving mechanism break, the worms and gears will act as a brake and will hold the axles and wheel attached thereto against rotation.

At one end of the tank 1 is a belt 21, which is formed by a plurality of buckets 2i? and the bases therefor, one. end of each base having a pair of ears 24, while the opposite end of the hase has recesses to' receive the ears of the next succeeding base and as the ears and that portion of the base having the recesses are provided with alining trailevers-elfv extending openings, the inlrmluction of a pin 2G through said opening will hingedlv secure the, bases together anil form an endless belt. the buckets serving as diggers as well as carriers.

That portion of the base havingr the ears 24 is reduced in width to form .shoulders QT, with which aie adapted to engage tongues 2S carried by a hearing head 2t), the periphery of said head being llattened to forni a pluralityY ot' faces il() and at the intersection of said faces are formed grooves 251, into which take the depending portions 32 of the ears 24 and the ends of the bases cooperating therewith, said depending portions and the grooves actingr as a sprocket wheel and chain for driving the beltV longitudinally, while the tongues engaging the shoulders 27, removes a portion ot' the strain from the pins entering the openings in the base and ears. At the. ends ot' the head .29 are guards 22) which .serve to guide the belt and also prevent the .soil from leaving the belt atthe sides when being discharged frein the buckets.

The head :20 is fixed to a rotating shaft 33 to which is attached a gear 34 and meshing with `said .gear is a pinion 35 attached to a slnl'ft 3o, said shaft being in turn attached to an)7 suitable source of power and through this medium, tht belt is driven longitudinally and ii order to properly guide the belt and cause the saine to engage the soil, said beltis directed over a frame 3i', which frame is pivotally mounted on the shaft 33 and extends a distance therefrom.

The soil engaged b v the buckets is carried upwardly and over the shaft. lil where it iS deposited into a chute 8S, from whence it descends into a receptacle tlf). and thence into a separating wheel 40, said receptacle 8!) being so arranged that any nuggets that may be contained in the soil, will be retained in said receptacle, that. edge of the separating wheel adjacent the receptacle 39 having a conical flange 41 into which the econtents of the receptacle are discharged and said contents are directed into the interior ot' the separating wheel by providing openings 42 at certain intervals in the tace 43 and at one end of the opening is arranged a guide plate 44, which guido plate causes the produc! retained by the flange. 11, to pass into the opening.

Positioned between the two walls 43 and 45 ot' the separating wheel 4() are spit-ally disposed plates 4G, 47, 4S and 49, said plaies being arranged in pairs and extended from a point adjacent the axial center of the separating wheel to the peripheral wall 51 thereof and said plates are held in their spirall arranged positions by introducing bolts through clips 53 carried by said spiral plates, said bolts alsoextending through the front and rear walls of the separating wheel;

The spiral plate 46, which paired with the plate li and the plate 4S, which is paired with the plate lil. are provided with perforations 54. while the plates 4T and 15) are solid and when the separating wheel is rotated.` the earth entering the openings 42 first encounters either the plate 4G or 48 and as said soil travels over said perforated plates. the tiner particles thereof and the minerals contained therein, pass through said perforated plates and onto the .solid plate -li and 49, thereby separating themixuerals and liner particles ot' the .soil from the gravel, etc., contained in 'the soil.

The tank 1 eontainsa predetermined quantity of water and a stream o water is constanthv flowing through the receptacle and into the separating wheel, the water and liner particles of the. soil passing through the channels 5 and 56 formed by the. plates -h and 4T and l5 and 49, respectively, the continued rotation of the wheel moving the product within the channels toward the axial center of the. wheel, where itis dis-V charged through ports 5T and 55 while the pebbles and argea' foreign particles are moved over tbe .surface ot' the perforated plates -lt and 4S and are discharged through ports .3T3 and o8 into a nozzle 59 at the axial center of the separating wheel, a suitable detiector (it) being provided to cause the gravel. ete., entering the nozzle, to more into.: a flared tube (S1 extending horizontally from the nozzle.

As the finer products and minerals leave the ports 5T and 5S, they are discharged into a chute (32. which is prefer-abi) inclined and provided with ritlles 63, the :inter end of the chute (32 terminating-over a wheel which is composed ot' a plurality of troughs 64, which troughs are curved and tangentially arranged around the hub of the wheeland are. also semi-circular in cross section, each, of .said troughs being provided with a pinrality of rillles (35,' which are so arranged as to provide substantially cupshaped pockets 66.

The ritlles (l5 are concav'e and in view' of, the rotation of the wheel, the current will be .stronger adjacent the ends of the rillles,

while the current at the center of the rifiles wiif be, very slight, thereby causing a whirl-- pool at each rittle, which will cause the different mineralsl contained in t? earth to separate from the Soil or sand aid the va.- rious minerals to separate from each other when the s ecitio gravity of said :minerals is ditferent, t 1e heavier minerals passing t0 the Y outer ends of the. rillles and die. lighter min-V erals being retained at the cent-ral portionof the ritlles. 1n this manner, we are end-' abled to successfully separate refractory ore.

rl`he troughs 64 are inclined from their inf' ner to their outer ends and the wheel composed by sind troilghs, is mounted upon'a,

iao

trucks are swung to a position at rieht angles to that Shown in the drawings, tnns dis posing the digging buckets at one side of the track-way and the carrying belt at the opposite side thereof. The drivin," power then disengagd from the trneks `ind applied to the operating parts of the maehne proper, the worms and wears on the trut-ks serving as brakes for holdin.;r the trurks in a fixed position. The thrust rod UH is then operated to briner one of the pinions 93 into engagement with the gear (715 to lower the end of the frame 3T and bring:r the buekets into engagement with the soil, when power is applied to the. mill proper, which will result in the buckets gathering the soil and depositing the same into the separating' wheel 40 through the chute 38 and nugget reeeptaele 3S). the

water deposited in the reeeptarle separatingr and softening the soil and gravel to such an extent. that they will readily separate. permitting the hear)y nuggets to settle to the bottom of the reeeptaele ltt. where they are retained, while the `ravi-l. ete.. will move into the ehannel formed by the llange all,v

where it is gathered by the guide plates l-l and moved into the interior of the separatingr wheel 40. 'lhe soil is then gathered up b v the )lates within the separatinjr wheel and the limer partieles of the soil separated from the larger partieles; they larger and smaller particles of the soil hein;r moved toward the Center o the wheel partiall)y by grai ity and partially by the torre of the water within the wheel and when the wheel has been turned to a prwleti'rminetl point. the smaller partieles of the soil and mineralsl eontained therein. togetherv with the water. are dis'- eharged through the ports at the axial eenter ot' the separatingr wheel and into the rhute G2. while the larger partieles and pebbles are dist-hanged into the tube til. where they are tleaned h'v the "otalion of the tube and moved to the outer "inl therrof. l'roni whenre they dest-end lhrongrh the funnel S5 and sleeve TN onto the belt rtf. than whew-e they are earrn-l to am suitable point to be diseharged.

'l`he liner pa the soil :unl the minerals alle." entering' the ehnte UL'. It-` srend iu said hote and Iass over the rillles. where a portion ol the minerals is extraeled from the soil. while the remaining portionof the minerals and soil -pass into the troughs below the lower end ot' the ehute and in View of the rotation ot' the troughs' and the man ner of plaeiner the ritlles therein. the major portion of the minerals' is mirarted from the soil and the dill'erent rlasses ot' minerals separated from eaeh other. 'lhe soil is then passed over the amalgam plate and any metals remaining therein is separated from the soil in this manner. The soil then passes onto the disk T4 'and is rennned from the disk by the-seraper T5 and diseharged into the drum 7G, the blades within said drum eax-uriner the soil u )wardly and disehargingr the same through the chute provided for receiving said soil.

Should the soil containing1r the mine als he shallow`l the entire separator may he moved slowly on its track ways by applying power to the wheels, but otherwise the separator remains stationary while the buckets and frame earrj.'in; r the same are graduallyr lowered until the mineralized soil is removed its full depth. when the. end of the frame is to be again raised. the machine moved to a new position, and the same operation again performed. It will further he seen that by :rotatably mounting the frame 2 upon the traek 4 as shown, the buckets and frame carrying; the same may he swung to opposite sides of the path ofthe marhine, that considerable surface ma)` be covered without neeessitating 'the moving.,1r of the maebine. ll'. will likewise he seen that b v providing the tank and arranging the parts therein as shown.the water within the tank may be used a number of times.
